Very easy site. Great service and quick release for download. Manuals are of good quality.

Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

Received a quick response, material was exactly what it was supposed to be. The service did everything I expected it to do. would use service again.

Detailed SONY CFD980 Service Manual at an easy to find one stop shopping. Make my radio hobby technically interesting. Thanks.

Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.
